CHIROPRAGTORS Application filed May 11,

This invention relates to a chiropractors folding table.

An object of the invention is the construe tion of a simple-and efiicient table that can be easily adjusted to suit the patient, and

which table can also be folded into a relativelysmall space for storage or transportation-or any other purpose.

Another object of the invention is the improvement of the head section of a table of this character.

A stillfurther object of the invention is to provide simple'and efficient bumper means for'the hinged body frame of the table.

5 Another object of the invention is the provision of a simple rack device which will hold the sliding body frame in different adjusted positions.

Withthe foregoing and other objects in View, my invention comprises certain novel constructions, combinations and arrangements ofparts as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

tional view of another bumper device, while Figure 11 is an elevated view of the auxiliary casing thereof.

Figure 12 is an enlarged sectional view taken on line 1212, Figure 3. 5 Referring to the drawings by numerals, 1' designates the primary section, 2 the auxiliary section, 3 the head section, 4 the hingedbody frame and 5 the sliding body frame. Thesections 1 and 2 are hinged at 6 (Figs. 2 and 3), whereby they may be folded together, as shown in Fig. 4; when in an open position, their contiguous ends are abutting.

Each of the two hinged sections 1 and 2 is provided with a pair of hinged legs 7. On the section, contiguous to the leg, is a depending tit, around which the upper end of the leg revolves. The substantially L- H shape hinge plate 9 is screwed to the upper end of the leg (Fig. 8) and is pivotally mounted on bolt 10. When the apparatus is in use, the leg is in a substantially vertical position, but when it is desired to foldup the apparatus, the leg is swung or pivoted around the tit- 8 parallel with the'section as clearly shown in F ig. 4. The L-shaped hinged plate is provided withan outstanding reinforcing web 11 for strengthening M the same.

The hinged body frame 41 is provided with metal bars 12 that carry rod 13. These bars 12 are mounted at 14-011 brackets 15 of the primary section. Preferably two head pieces 16 are mounted at their inner ends on rods 13; these head pieces 16 can slide on said rods. A rod 17 is also on said head pieces near their outer ends. These head pieces can be adjusted relative to each other to accommodate the face of the patient resting upon the apparatus. Abracingbracket 18 (Fig. 6) is placed at the center of rod 13, preferably between thehead pieces 16. Pivotally mounted on rod 17 is a rack bar 19. This a bar is provided near its upper end with an integral apertured lug 20, in the aperture of which is pivotally mounted catch 21 for the purpose hereinafter specified. The teeth 22 of rack bar 19 are adaptedto engage and. be passedover theedge'of plate 23 (Fig. 7). A

guiding spring plate 24 is fastened in the aperture 25, through which rack bar 19 passes, holding the rack bar efficiently in place. The rack bar drops of its own weight into engagement with the plate 23, so that the head section 3 can be easily adjusted to different positions. When the entire apparatus is folded as shown in Fig. 4, the catch or hook 21 is hooked into eye 26 for holding the head section 3 in position.

On the under face of the headpieces 16 (Fig. 12) I fasten on one of said pieces a plate 27 that is provided withan aperture 28. On the other head piece, place a lug or catch 29, over which the outer end of plate 27 is adapted to pass until the catch enters aperture 28 which will then cause the head pieces to be held together. A grip 30 is formed on one edge of plate 27 to facilitate the manual raising of the outer end of plate 27 to unlock the sliding head pieces 16 to permit same to be separated or spread apart on the rods 13 and 17.

The bumper device for the hinged body frame 4 shown in Fig. 5 comprises a board 31 layed upon the stringers 32. Each stringer 32 is providedwith a longitudinally extending slot 33. The board 31 is provided with bolts 34 (Fig. 2) sliding in said slots, so that the board is held in an adjusted position upon said stringers 32. The board 31 is provided with a plurality of sockets 35 in which the lower ends of coil springs 36 are positioned. The upper ends of said springs project into similar sockets 37 formed on the board 38. Therefore, it will be seen that when the weight of a body is on the hinged body frame 4 and it is bounced o otherwise pressed up and down, the frame will hit against board 38 which acts as a bumper to take up some of the shock and thereby make the treatment more agreeable to the patient.

To prevent the outer unhinged end of body frame 4 from having too much rebound, after striking the bumper device, and to also serve as a means for limiting the hinging movement of frame 4 upon rod 13, I fasten (Fig. 5) the lower ends of flexible members 39 to the primary section and their upper ends to the hinged body frame 4. A coil spring 40 is placed between said section and frame; this spring is provided with end loops 41 through which the flexible members 39 extend. Ooil spring 40 keeps the flexible members 39 taut, but allows certain movement of the outer end of the body frame 4. This unique device, comprised by said members 39 and spring 40 constitute a brake means for preventing too much vertical movement of body frame 4 and also constitutes means for. retaining said frame close to the other units of the table when folded, Fig. 4.

p In Figures 10 and 11, I have shown an-.

ing the parts together.

other embodiment of the bumper device and it will be understood that I may use as many of these devices as I desire on the primary section 1 and the hinged body frame 4. This bumper device comprises a primary casing 42 extending through the prlmary section 1. The upper end of casing 42 is slotted at 43, producing bent over wings 44 on the outer end of which is a horizontal flange 45. Bolts 46 secure both flanges to the primary section 1. In primary casing 42 is mounted auxiliary casing 47. Around auxiliary casing 47 is coil spring 48. The lower end of coil spring 48 bears against the sleeve 49 within the lower end of casing 42. A collar 50 is around the upper end of auxiliary casing 47 and the upper end of. spring 48 bears against same. The auxiliary casing 47 is provided with a pair of slots 51, in which large cotter pin 52 works. This cotter pin 52 is passed through the primary casing 42 and sleeve 49. A coil spring 53 is in the lower end of auxiliary casing 47 with its upper end bearing against cotter pin 52 and its lower end around bolt 54. An angle bracket 55 is fastened to the under face of hinged body frame 4 with an extension .56 projecting into the top of auxiliary frame 47. A bolt 57 extends through collar 50, casing 47 and extension 56 secur- WVhen weight is placed upon body frame 4, spring 48 will be depressed, but when the weight or pressure is removed, spring 48 will force u wardly on body frame but not too suddenly, because of spring 53. r

The sliding body frame 5is provided with two slotted cleats 58, fastened on the under side. Each cleat is provided in its side face with a longitudinally extending slot 59 (Fig. 9). In slot 59 is a track 60. The tracks 60 are fastened to the inner faces of the auxiliary section 2. Therefore, it will be seen that the sliding body frame can be moved longitudinally of the auxiliary section without fear of displacement unless drawn too far outwardly. This longitudinal adjustment is desirable for accommodating difierent size patients on the table. On the bottom of one of the slotted plates 58, I fasten a rack plate 61. This plate 61 is provided with a plurality of openings 62 formed by cutting away the, metal, producing downwardly extending tongues 63 over which the inner end of pivoted catch .64 rides. Catch 64 is mounted on bracket 65, Fig. 9. As the body frame 5 is pulled outwardly, the operator can reach under and hold the catch 64 from engagement with the rack plate 61, but upon releasing the catch, it will ride at its inner end into one of the openings 62, thereby locking the body frame in the desired adjusted position. When thebody frame is pushed inwardly, the catch device will ride freely over the rack plate for permitting the quick closing, so to speak, of the body frame upon the auxiliary section. This rack device constitutes fastening means for holding the body frame 5 in adjusted positions upon the auxiliary section.

On the sides of the sections, I place hand grips 66 for enabling the easy handling of the apparatus.

The primary, auxiliary and head sections are suitably upholstered as shown in Fig. 4:. When it is desired to fold the table, as

shown in Fig. 4, the legs 7 are closed in, parallel with the sections and the primary section is hinged or folded in under theauxiliary section, with the head section folded upwardly and hook 21 fastened in the eye 26.

In operation, it will be seen that the patient can recline on the table, and by means of the adjustability of the sliding body frame and the head section, the apparatus can be adapted to the size of the patients body and then the patient can be treated for the best results.

While I have described the preferred embodiments of my invention and illustrated the same in the accompanying drawings, certain minor changes or alterations may appear to one skilled in the art to which this invention relates, during the extensive manufacture of the same, and I, therefore, reserve the right to make such changes or alterations as shall fairly fall within the scope of the appended claims.
